To all whom, it may concern:

Be it known that I, AUGUSTINE BALDw1 ,a citizen of the United States of America, and a resident of New York city, county and State structure and being the base on which the bales are compressed by a platen located above and operated by an inverted doubleacting steam-cylinder mounted at the upper extremity of the structure to facilitate handling the bales on the ground-floor, [so as to avoid hoisting and the more expensive upper structure necessary when the reverse construction is employed,particularlyin the case of presses of twenty feet and more'in height,as contemplated in my plans; but in some places it may be preferred to reverse the machine, as

where it is to be located in the side of an embankment, as hereinafterdescribed,reference being made to the accompanying drawings, in which Figure l is a front elevation of my improved press with the platen up. Fig. 2 is a side elevation. Fig. 3 isa diagram of the compoundlever mechanism detached and represented in the positions they assume when the pressing is completed. Fig. 4. is an end elevation of the face-plate of the platen. Fig. 5 is a front elevation of the face-plate-of the base on a larger scale and with the middle portion broken out. Fig. 6 is a plan view of the faceplate of the bed, also enlarged and with the middle portion broken out. Fig. 7 is a horizontal section of the press on line 2 2 of Fig. i 1 with some parts omitted. Fig' 8 is a detail in elevation, partly in a central section,on line 3 3, Fig. 7.

A represents the base, whereon the faceplate B is placed, between which and the faceplate 0 of the platen d the bales are compressed. The base A supports four long posts e, at the upper ends of which the inverted steamcylinderfis mounted,also shorter posts g, at the upper ends of which and on the posts e four pivot-supporting blocks 72. are mounted at the four corners of the plan, respectively. (See Fig. 7.) These blocks of the frontand rear sides of the press, respectively, are coupled by the tension-bars 't' and the drop-stays j, being bolted thereto by the projecting ends of pivot-rods It, on each of which is a pair of levers Z, the free ends of which meet at the center of the machine and are coupled by links m with the cross-head n, and said levers are also coupled by other links 0 with the platen (1, said platen being mounted by guide lugs 19 on the posts 6 to slide up and down freely. By the employment of the outside posts 9 in addition to the posts 6 and the lever-pivot-supporting blocks h, attached to both sets of posts, much greater holding power for the pivots is obtained and the pivots may be located at a greater distance from the center line in which the power acts, which permits of longer levers land of the corresponding arrangement of the links 0, pivoted to;levers h intermediately of the fulcrumpivots of said levers and their connections with links m. The fulcrum-pivots 7c are inserted in the blocks it between the posts, and the tension-rods 'i are connected by said pivots ina simple but at the same time most sub stantial construction.

Guideway-grooves q for the cross-head are formed in housings s, which are supported at the upper end by arms 75, clamped on posts 6, and lower down are bolted to the tension-bars t' and the drop-stays j, the chief function of the latter being to support the lower ends of the housings.

The links on are connected to the cross-head by a pivot-bolt w, extending through the crosshead at lengthwise and through the end portion of the piston-rod y, inserted in the crosshead. Spacing-collars a are placed on pivotrods 76, by which, together with the inner surfaces of the blocks 71, the said levers are confined. Recesses a are formed in the upper surface of the follower to let in the ends of links 0 to connect with pivots b.

The face-plate C of the platen is recessed, as indicated at c, Fig. 4, to receive the upper portion of the bale, and together with the face-mam B of also recessed,v G Qn; stitute a practically inclosing box when th bale is reduced tothe final dimensions" and.

- than when the common plain unrecessed facerises, the-side e and the end f are hinged, as at g.', to turn down and allow the bales tto be shoved on and off without. obstructiom When closedup, theseisides aresecured by the'in-, terlocking keepers h andi.

Both the face-plates are grooved in their faces, as at j, for reception of the bands, and

the sides are notched at k coincidently with "said grooves for allowing the bands to be wrapped around 'the pressed bales and tied.

The dotted line 9 indicates the osition of the surface of face plate when the bale is. completely'pressed, the levers land connect-f 1 il'lglihks being then in the posit-ions repre- "sented in Fig. 3. v

To facilitate drawing the bands tightly, a

shaft Zis mounted'on thefront side of the" face-plate O of the platenin suitable bearing lu s mto be turned bya crank applied at one end and provided with a'hoIding'rat'chet it and pawl 0 for so drawing them, the bands beiug' coiled on the shaft, so as to bind by ay be' of any approved kind suitable for be-' ing operated by hand or otherwise and is not claimed herein nor d-efin'itely show'n in the drawings, For a general understandingof it,i't may, however, be stated that q repre sents the live-steam pipe; 8, the lower valvechest; 15, the upper valve-chest, and u the resented atlv.

. be considered as providedgWit-h'the usual 'wiper cams for lifting the valves in the'u'sual manner of such well-known valve a aratus.

At each end of the steam-cylinder is a relief valve at, which opens into a pipe y, connect ed with the live-steam pipe to relieve excess ive compression of the steam -oushi-on by To facilitate deliveryof the bales from face plate B, on whichthey rest when the platen,

Check-valves b are connected in the pipes y',intermediately of the relief-valves and thelive steam for intercepting the steam which would otherwise be in .constant communication'with the relief-valves, which is not desirable.

In the operation of the press, starting with the piston at the upper endof its stroke and .theplaten at the upper extremity of its movement, as seen in Fig. 1, the movement of the piston will be from the position of min Fig. .1 to min Fig. 3, while the movement ofthe platen will only equal the vertical descent of pivots a, swinging around pivots it, somewhat less than half the travel of the iston,,;with corresponding increase of power.

' I am aware that various cont-riva ees of toggle joints and compound levers have been I employed for multiplying thepower of the piston 'onthe platen; butI am not aware that the construction shown and described by me herein has ever before been used. r
